It’s always good talking about jQuery as it’s relatively straight forward for the audience to read and has a shallow learning curve (if you know CSS already). One of the other pleasures talking about jQuery, and other front end tech, is that you can always show interactive demos to “wow” the audience…

Here are my slides followed by a link to my demo code:

I brought some of my demo code up to date showing examples using the live, event delegation functionality with jQuery. You can view my demo here or download it zipped here.

If you have any queries about the above or want assist you in a jQuery, Javascript and AJAX project contact us.

Spring Integration

Jonas Partner from OpenCredo also gave a presentation on the evening on Spring Integration. His slides are below:

We were treated to practical demonstrations by Rob Harrop from Spring Source on Building REST applications with Spring Framework 3.0 and Jan Machacek from Cake Solutions on Building an application using the Spring Framework 3.0. The video of both talks can be seen at, http://vimeo.com/channels/opensourcecentral. The code for Rob’s talk can be found at http://github.com/robharrop/restlist/tree/master or for checkout users can simply do: git://github.com/robharrop/restlist.git. Jan’s code can be found at http://www.cakesolutions.net/teamblogs/2009/04/09/sug-source-code/.

The topics most requested for talks in future events were OSGI, Groovy and Spring security, we are actively arranging talks on these subjects. The consensus was that the SUG North West be run bi-monthly so the provisional date for the next meeting is the 3rd June 2009 at the same venue. If you want to be kept in the loop for future events or announcements please join the LinkedIn North West Spring User Group, e-mail me at guy@springusergroup.org.uk or visit the SUG website at http://www.springusergroup.org.uk/.

1. Securing Spring web and WS applications.
2. Introduction to OSGi with Spring Dynamic Modules and dm Server
3. Spring on the server side, Ruby on the client

Securing Spring web and WS applications

In this talk, we will take an existing, well-written Spring web application and crack it. We will use Mallory’s services and show script and XHTML injection, cookie stealing, the “other four” HTTP methods and — Mallory’s favourite — SQL injection.
Next, we will take another Eastern European, Eve, and we’ll show how we can snoop on WS messages, we will demonstrate how Mallory can modify the message. We will also show how we can cut Eve out and how we will detect that Mallory is making changes to our messages.
You’ll experience our Eastern European team at its dark, foreign and generally menacing best

OSGi, Spring DM and dm Server

We have done quite a bit of development using the dm Server and OSGi. We can show how to make most of OSGi in your new applications. We will show the usual tricks of updating dependencies at runtime, we will also show OSGi fragments and dynamically extensible web applications.
You will see web applications deploy and update in seconds!

Spring on the server side, Ruby on the client

This should please all of you out there who think that Java web applications with servlet, JSPs, taglibs, and all that are just too complicated for the task. In this talk, we’ll show how to have a complex (and easily load-balanced) services tier in Java and Spring and how to make the most of the agility of Ruby on the client. You’ll see loads of JSON and REST.
If time permits, we may sprinkle it with memcached magic dust.

Please comment

So, please help me decide which talk would go down the best. I look forward to your comments either in this blog or on my e-mail.

• Performance monitoring approaches
• Top 3 Hibernate tips
• Web application security
• Five interesting applications
• And one more thing that I can’t remember any more

From this list, the attendees selected the first two items; I have prepared a talk that covers the two topics. Download.
